Legal help for AI and SaaS startups, stage by stage: what to do yourself and what to hand off

In short

An AI or SaaS startup doesn't need a law firm on day one, but it does before certain events: bringing on a co-founder, taking anyone's money, paying someone to write code, collecting user data at scale, and signing a contract a customer wrote. Plenty of early admin can be handled yourself. Spend legal budget on ownership, equity and the first contracts that bind you to other people, because those get harder to fix every month you wait.

Solo founder building an MVP

Often you don’t need a lawyer yet. If you’re one person testing an idea, haven’t incorporated, aren’t collecting real user data and nobody else is working on the product, there isn’t much to protect. Spend your time on customer conversations.

A few habits save money later:

  • Keep the code in a repository you control, under your own account or your future company’s.
  • Don’t let a friend “help with a few features” without a short written agreement about who owns the work.
  • Search your product name before you fall in love with it. A basic trademark search costs little compared to a rebrand.
  • Read the terms of every AI tool and API you build on, especially what they say about your inputs and commercial use.

A second person arrives

The usual trigger is a second person. Once someone else contributes time, code or money, you have to decide who owns what, and that’s where most early disputes start. This is worth paying for:

  • Incorporating with a share structure that works for future investors. See federal or Ontario incorporation.
  • Issuing founder shares with vesting, so a co-founder who leaves in month four doesn’t walk away with half the company. See founder vesting.
  • Having every founder assign pre-incorporation IP to the company.
  • A shareholder agreement covering decisions, departures and transfers.

What you can handle yourself: keeping the minute book organized once it’s set up, routine annual filings, and tracking your cap table in a spreadsheet, as long as it matches the corporate records.

Contractors and your first employee

Hiring is where AI and SaaS startups quietly lose ownership of their product. Under the Copyright Act, employers are generally the first owners of work employees make in the course of employment (section 13(3)), but contractors and agencies own what they create unless they assign it in writing (section 13(4)). A freelance developer paid by invoice with no agreement may still own the code. See who owns code a contractor writes.

Build a contractor template and an employment template once, then reuse them. Misclassifying someone who is really an employee is the other common problem; see employee or contractor.

As you grow, check Ontario’s job posting rules. Since January 1, 2026, employers with 25 or more employees that publicly advertise a job must disclose in the posting if they use AI to screen, assess or select applicants (Employment Standards Act, 2000, s. 8.4 and O. Reg. 476/24; see Ontario’s guide). If your recruiting stack uses AI, check before you post.

Template terms and privacy policy

For a closed beta with a handful of friendly users, a carefully adapted template is a reasonable stopgap. Before a public launch, and certainly before you charge money, your terms and privacy policy need to describe your actual product: where data is stored, which AI providers see user inputs, how billing and cancellation work, and what you promise about uptime.

Two places templates tend to fail software companies:

  • Marketing emails. Under CASL, implied consent from a demo request or other inquiry lasts six months, and from a purchase or contract two years. Templates rarely set up your signup flow to capture express consent. See CASL for SaaS.
  • AI features. Generic terms don’t deal with training on customer data, output accuracy or your model provider’s terms. See AI product terms.

Signing an enterprise customer’s contract

This is where many founders move from “nice to have” to “need.” Enterprise paper is written to protect the buyer. Terms that hurt small software vendors include unlimited indemnities, uncapped liability for data breaches, broad ownership of “deliverables” that can sweep in your platform, and security commitments your team can’t meet.

You can triage simple contracts yourself: a mutual NDA on standard terms, or a click-through agreement for a tool you can easily replace. Send the first few customer agreements, anything over a value you set in advance, and anything involving personal data to a lawyer. Over time you’ll build a playbook that lets you handle more yourself. See SaaS agreements.

Raising money

Fundraising isn’t a do-it-yourself stage. Even a small friends-and-family round needs proper documents, whether it’s a SAFE, a convertible note or priced shares, and investors will review your corporate records, IP ownership, key contracts and privacy practices.

The items that slow rounds down are almost always from earlier stages: missing IP assignments, unsigned board resolutions, shares promised by email but never issued. Fixing them under deal pressure costs more than doing them when they first came up. See getting investor-ready.

Keeping costs predictable

Ask for a fixed fee for each defined piece of work, agreed before it starts. When contracts, hiring and privacy questions arrive every week rather than every quarter, look at ongoing legal help.
